Organic peanut butter, pizza and frozen fruit were among the 313 private-label products Roundy's, Milwaukee, Wis., added to its private-label line this year.

Minneapolis-based Target also announced plans to introduce organic groceries under its Archer Farms company-brand at the company's SuperTarget stores and select discount locations. It's to include whole-grain pizzas, pastas and fruit strips.

Ethnic lines, like the one marketed by Eden Prairie, Minn.-based wholesaler/retailer Supervalu, were also expanded.

The retailer almost doubled the size of its Tex-Mex offering when it added 30 items, including authentic spices and peach salsa, to its Carlita private-label line.

Lower-than-necessary price points continued to contribute to sub-par consumer perceptions about company-brand products, according to the IRI's study: “Understanding Emerging Trends and Key Success Factors in Private Label.”
